Bug#909272: Please provide checks for spotting wrong indentation of paragraph separator

[s3v <c0llapsed@yahoo.it>]

Package: lintian
Severity: wishlist


Dear Maintainer,

 I would like to ask you to provide some checks for spotting wrong indentations
of paragraph separators into long descriptions.

E.g.

Package: python3-ghost
Description-md5: c97396987883115e33c12a7995af18f6
Description-en: webkit web client library
 Ghost.py is a scriptable web browser as Python library, based on
 WebKit. It support JavaScript and can be used e.g. for testing,
 web scraping, and automation.
  .
 This package provides the Python 3.x module.

As you see, the paragraph separator, i.e. a single dot, is wrongly indentated
(two spaces from the beginning of the line rather than only one as per Debian
Policy [1]).

Side effects:
[a] package descriptions at packages.d.o look pretty ugly [2]
[b] "misindentated" dot is not recognized by DDTP as a valid separator and
    this issue leads into more work for translators since identical paragraphs
    are automatically translated by the system but in this case they are not
    (e.g. the sentence "This package provides the Python 3.x module." for the
    package above).

Occurrences currently involved:

 $ sed -nr '/^  +\. *$/p' Translation-en | wc -l
 91
 $ sed -nr '/^  +\.$/p' Translation-en | wc -l
 91


Thanks for reading and kind regards.
